ing the lever attachment for operating the Same.

Corresponding and like parts are referred to in the following description and designated in all the views of the accompanying drawing by the same reference characters.

Let the numeral 5 represent a gas engine meral 7 represents the intake, or manifold thereof, the manifold 7 being connected in communicating relation with a carbureter 8 through a passage 9.

A water vaporizing chamber 10 is applied to the exhaust pipe 6 and is in communication with the upper portion of the radiator 12 of the engine through the medium of a pipe 13, through which pipe 13, water is fed from the radiator to the vaporizing chamber 10. The vaporizing chamber 10 is also in communication with the passa e 9, from the carbureter 8, through the me ium of a pipe 1 1.

The vaporizing chamber 10 comprises an outer tubular housing 15, having a segmental base 16 integrally formed therewith, which receives and rests against the exhaust pipe 6. The extremities of this base 16 project beyond the housing 15, said extremities being engaged on opposite sides of said housing 15 by means of fastening bands 17, which pass around the exhaust pipe 6 and hold the vaporizing chamber 10 on said exhaust pipe. These bands 17 are brought together at their extremities and fastened, as shown at 18. A valve sleeve 19 is received. in the housing 15, and is; revolubly mounted therein. The inner extremity of this valve sleeve 19 is provided with an outwardly extending flange 20, which is formed integral with the said valve sleeve, said flange resting against a shoulder 21,

which is formed on the interior of the housing 15. The engagement of the flange 20 with the shoulder 21 serves to hold the valve 'sleeve 19 against outward movement in a longitudinal direction. A cap 22 is threaded in the outer extremity of thevalve sleeve 19 and forms a closure for the outer extremity thereof. The cap 22 is provided with an annular flange 23 thereon, which engages with a shoulder 24 formed on the interior of the housing 15 near the outer extremity of the latter. The engagement of this flange 23 with the shoulder 22 serves to prevent the valve sleeve 19 from longitudinally moving in an inward direction. The outer surface of the cap 22 lies flush with the outer extremity of the housing 15, whereby a lever 26, which is integrally formed with said cap 22, may be extended beyond the outer surface of the housing 15 at right angles to the latter. This lever 26 is connected with a member 27 which is extended to a position in convenient reach of the operator of the engine. The valve sleeve 19 is operated through the medium of this member 27 and the lever 26 to control the induction of the vapor to the engine. The member 27 is of sufficient rigidity to be pushed backward for operating the valve 19 in the reverse direction.

One extremity ofthe pipe 13 is in communication with a port 28 in the housing 15,

which said port 28 is adapted to register with a port 29 in the valve sleeve 19. The port 28 of the housing 15 leads through a nipple 30, to the upper extremity of which, the pipe 13 is connected by means of a coupling collar 31, threaded on the nipple 30, as shown at 32. A valve piece 33 is threaded in the nipple 30, as shown at 31, and is adapted to be projected into the port 28 to control the flow of water therethrough into the vaporizing chamber 10. The induction of water into said vaporizing chamber 10 may be entirely shut off by closing the valve, or the induction of water may be regulated by said valve piece 33 in accordance with the amount desired to be admitted to said vaporizin chamber. The-pipe 13 is downwardly inclined from the radiator 12 to the nipple 30, whereby the water will flow by gravity from the ladiator to the vaporizing chamber 10. The upper extremity of the pipe 14 is in communication with a port 35 formed in the housing 15, which port 35 is adapted to register with an eduction port 36 formed in the valve sleeve 19. An air induction port 37 is formed in the housing 15, which is adapted to constantly register with an induction poft 38 formed in the valve sleeve 19, the port 38 being of greater length than the port 37, whereby the valve sleeve 19 may be revolved for the purpose of registering the ports 29 and 36 of the said valve sleeve with the ports 28 and 35, or for moving the ports 29 and 36 of the valve sleeve out of register with the last named ports, and at the same time constantly maintain the ports 37 and 38 in register. The ports 29, 36 and 38 are circumferentially in line with each other, and when the valve sleeve 19 is rotated, describe a path intersecting the ports 28,35 and 37 of the housing 15, which said ports are also circumferentially in line with each other.

The lever 26 is extended between two stop pins 39 and 40, which are positioned on the outer extremity of the housing 15. We will assume that the lever 26 in Fig. 1 occupies that position there shown when the ports 29 and 36 of the valve sleeve 19 are out of register with the ports 29 and 35 of the housing 15. Now, by pulling on the member 27, the lever 26 will bemoved against the stop pin 40, causing the valve sleeve 19 to revolve and register its ports 29 .and 36 with the ports. 28 and 35 of the housing 15.

Thus, water from the radiator 12 will flow through the pipe 13 and pass through the registering ports 28 and 29 into the vapor-v izing chamber 10. This chamber is at a high degree of temperature under the influence of the exhaust through the exhaust pipe 6, and

instantly the water enters the said chamber 10, it will vaporize under the influence of the high temperature within said chamber. The vapor, together with a mixture of air which is taken in through the ports 37 and 38, will then pass from the chamber 10 through the ports 29 and 35 and the pipe 14: into the manifold 7 of the engine, this mixture entering the manifold 7, as well as the cylinders of the engine, forwardly of the induction of the gas from the carbureter 8, the induction extremity of the pipe 14 being in communication with the manifold 7 above the carbureter 8 for that purpose.

By the proper adjustment of the valve 33, the water may be fed into the chamber 10 very slowly, or drop by drop, thereby creating a relatively small volume of vapor to be fed into the engine cylinders.

The use and operation of the invention, as well as the functions intended to be accomplished, have all been explained in the foregoing description with reference to the structural features of the invention, and it is believed that this description is sufficiently complete and exact, wlthout further description, to enable persons skilled in the art to readily understand the same,

While I have described and illustrated herein, a specific form of my invention, it is understood; that I am not limited thereto.
